Description

There’s one problem with Gravatars. They are very slow to load. Each page with comments on them makes one call per comment to the Gravatar server. While a single call takes only a 100ms, on a page with hundreds of comments, we are talking about major slowdowns. Page loads can take 20 seconds and more.

This plugin solves this problem by:

caching gravatars with WordPress cron job..

caching gravatars on comment submission

maintaining a single copy of the default gravatar instead of downloading it again and again for all the email addresses with no gravatar associtated

Gravatars are not caching properly

Hit the “Empty Cache” button to clear the cache database and clear out the cache directory by hand (you can see the path at the very top of the Settings screen). Then hit the “Run Cron Now” button, it will refresh a couple of gravatars, so you can check the cache directory again, to see if it’s filling up correctly. “Current Cron offset:” will increment, so you can track the progess and see how the cron is running. You can also turn on “Debug mode” and check log.txt afterwards.

Generated (Itenticon, Wavatar and MonsterID) gravatars are not working correctly!

These types of gravatars are not currently supported. Drop us a note and we might add this feature in next release.

I want to have bigger gravatars on author profile pages. Your plugin supports only one gravatar size. Is there any workaround?

You can turn edit your template to turn off the FV Gravatar Cache just when needed, add this code right before that section in your WordPress template php file:

This plugin works well and increases speed but the problem is it only caches images for the registered users. I want to cache for every user who comments on my page. (They Don’t need to login to comment on my website instead giving their name and email id is enough)
